Thin Filament-Reconstituted Skinned Muscle Fibers for the Study of Muscle Physiology
Figure 4
(a) Phase-contrast image of cardiac myofibril treated with gelsolin. Myofibril was held with two glass needles. Thick needle was moved to the left to stretch the myofibril and force was measured by the bending of the thin needle. Scale bar: 10 μm. (b) Stress-strain relationship of myofibril treated with gelsolin. Two examples are shown. Strain is expressed relative to the slack length.
